PNEUMATIC W-lNDlNG APPARATUS FOR PRINTING-TELEGRAPHKS.

, SPECIFICATION forming part of Letters Patent No. 316,688, dated April28, 1385.

(No model.)

To all' whom it may concern.-

Be it known that I, HENRY VAN HoEvEN- BERGH, a citizen of the UnitedStates, residing in Elizabeth, in the county of Union and State of NewJersey, have invented certain new and useful Improvements in WindingDevices for Printing-Telegraph Receiving-Instruments, of which thefollowing is a specification.

My invention relates to a class of inventions employed inl connectionwith printing-telegraph instruments for supplying the force necessary toactuate the same.

The object of the invention is to provide means for conveniently storingany required amount of energy and causing the same to be automaticallyapplied to the instrument at such times and in such quantities as may berequired,

The invention consists in organizing the apparatus substantially asfollows: Applied to a printing-telegraph instrument of any convenientform is a spring or a weight designed to be wound up by means of apinion and a rack-bar applied thereto. The rack-bar is impelled in theproper direction for winding the spring by means of a system ofpneumatic tubes and air-chambers or bellows. For this purpose a primarybellows is employed,which is equipped with a tread1e,whereby theoperator may conveniently actuate it. By means of this bellows air isforced into a storage reservoir or bellows, and from this bellows it isled to a third air-chamber or bellows, which is employed for actuatingthe rack-bar which is carried thereon. This last-named bellows is`provided with an automatically-operating fro movement of thewinding-bellows the valve which permits the air to escape therefrom isclosed when the bellows is compressed, and is again opened when it hasbeen completely expanded.` The valve leading from t-he storage-chamberto the winding-bellows is For the pur-V also automatically opened afterthe bcllows- 5o valve has been closed, and it is itself closed beforethe bellows-valve is again opened, thus affording an intermittent supplyof air to the winding-bellows. For the purpose of automatically giving asignal when the air contained in the storage or supply chamber is nearlyexhausted, I employ a circuit-closing device, which servesat that momentto complete the circuit-connections of a local battery through analarm-bell, thus giving warning to the receiving-operator.

In another application of even date herewith, Serial No. 139,87 6, Ihave shown certain lparts shown and described herein, but the partsherein claimed are not claimed in said other application.

In the accompanying drawings, Ifigure l is an elevation showing theorganization of the pneumatic chambers and their connectingtubes. Fig. 2is a side elevation showing a 7o portion of a printing-telegraphinstrument, together with the device employed for connecting thepneumatic apparatus with the same; and Fig. 3 is an end elevation of they same. The invention will be described in connection with areceiving-instrument,@though it may be applied to a transmitter.

Refeng-to the drawings, A represents a base upon whiclrthe several partsof a receiving-instrument aresupported. This instrument is of anywell-known construction, and is designed to be actuated by means ofaspring, C, which is carried upon a shaft, c. and communicates itsmotion, through a system of S gear-wheels, to an escapement-wheel, d.

For the purpose of winding the spring`C a pinion, e, is applied to theshaft c, and it is coupled thereto by means of a ratchet-wheel, e', andpawl e2, in a manner well understood. Applied to thepinion eis arack-bar, f,which is driven longitudinally by meansjof the pneumaticapparatus hereinafter described. The parts are so organized that duringthe upward movement of the rack-bar the ratchetwheel e will be engagedby the pawl e2 and the spring will be wound. During the downwardmovement of the rack-bar, however, the

ratchet-wheel e will'be allowed to turn freely, and no resistance,therefore, will be oficred to the descent of the rack-bar.

For the purpose of actuating the rack-bar the following system ofpneumatic apparatus is employed: A bellows, p', provided with a treadle,r,is locate'd'i'u `a convenient place relative tothereceiving-instrument, so that the operator may at any time actuate'thesame.

1c A spring, r2, normally forces the trea'dle upward, and by means of'the vdownward pressure exerted by the foot upon the treadle and thereturn movementoccasioned by the spring the bellows p may be alternatelycompressed i5 and expanded. A valve, s', is applied to this bellows in awell-known manner for permit- .ing the sam-e to be iorcedoivitwardthrough a 2c tube, t, when the bellows is compressed. The

tube't leads to a storage-bellows, p2, in which l `it is designed that aquantity ot' air received trance of the tube t into the bellows p2.

3o the purpose of placing the air contained therein under suflicientpressure to accomplish thc winding ofthe spring C, in the mannerhereinafter described. An outlet-tube, t2, -leads .from-the bellows p2to a third bellows, p3. In-

3 5 seitcd within the tube #is 'a centrally-pivoted -valve, s3, which isso constructed that the force .ict lthe air passing through the tube t2will not 4o nor open it if it is closed.

4 5 formed an elongated opening or loop, a3.

actuate it in either direction-that is to say, the air will not closethe valve if it is open,

A crank, a', connects the arbor of the valve s with a pitman or rod, a2,extending in..a direction parallel yto the direction of :movement of theupper portion of the bellows pi", In the rod a2 there is arm, a4,extends A.from the outlet-valve s of the bel-lowsv p3 rthrough the loopai. This arm 4is .engaged by the upper Vextremity of the loop """wwwwhenthe bellows lis expanded, therebyforcing 5o the vavesto open, afterhaving irst caused the valves to be closed, by turning the crank a1.throughrthe arm a2, sion of the bellows p the arm ais engaged by 4.thelower-end of the loop a3., and the valve sL .fis thus-closed. The samemovement of the ,bellows also causes the roda2 and the crank atoopenjthe valve-s. Airesh supply of air is thusadmitted to the chamberp, which immediately exp'ands. At the upper limit of its 6o motion thevalve sg-is again closed and the valves,4 opened, and the operation isrepeated. Sollong, therefore, as a supply of air is contained Qinthe'b'ellows p2, the bellows. p3 will bel The movements of the upperportion of the bellows alternately expanded and compressed.

For the purpose of causing an alarm to be automaticall given when thebellows p2 is nearly exhausted, I employ a local battery, W', one poleof which is engaged through a conductor, l, with a'contact-spring, w',carried upon the stationary portion o1" the bellows The bellows pf willthen. be
